INTRODUCTION

Founded in 1984, SWR specializes in quality amplifiers and speakers addressing the needs of the professional and semi-profes-

sional bassist. Widely known as the makers of the finest bass systems in the world, SWR has recently gained popularity among

instrumentalists of all types, stemming from the introduction of a series of products intended for the acoustic musician. SWR and

its advisory board, consisting of some of the world's finest musicians, have constantly strived to identify the changing needs of

musicians everywhere, and to respond with new and useful designs, each one unique unto itself.

Numerous requests from our customers to produce a line of products that would incorporate accurate sound, high reliability, quali-

ty components, hand-made craftsmanship, and an overall low price, resulted in the development of the Workingman's Series of

amplification from SWR.

The precision electronic section featured in the Workingman's Series of amplifiers is entirely hand-built, employing a variety of

technologies selected for their sound quality and practical usefulness in a roadworthy and studio-ready amplifier, including an all-

discrete initial gain stage in the preamplifier section and discrete solid-state design in the power amplifier. Regardless of its lower

price, the Workingman's Series offers no compromises of the essential SWR design and construction philosophy. Corners are not

cut from a more elaborate model: rather, each product's design parameters are conceived from the ground up and the best avail-

able components are selected for each application. Once again, with sound, reliability and price consciousness in mind.

The tone-shaping section of all Workingman's Series amplifiers, including the Aural Enhancer (found in all SWR Preamps and

Integrated Amplifiers) and the Tone Controls, will not impose a character on your sound. They will instead make the interface

between your instrument and the speaker system (two of the largest factors in your final tone) a simple matter requiring minimal

effort. The center frequencies of the Tone Controls were chosen for their musical effect on most basses.

SWR amplification is handmade and individually tested in the United States. Everyone at SWR sincerely hopes that you are satisfied

with your recent purchase, as we are extremely proud of the quality and attention that goes into each and every SWR product. We

truly hope that your purchase of an SWR helps bring out the best in your playing and adds to your enjoyment of music.

WORKINGMAN'S 2004 - FRONT PANEL FEATURES

BALANCED DIRECT RECORD OUT

The Balanced XLR output is a true balanced output. No front panel controls affect its signal. The tone and output level are con-

trolled only by the instrument plugged into one of the input jacks. To use this feature, run an XLR (Cannon) cable from the Balanced

D.I. to the input of a tape machine, mixing console, etc. This output is also suitable for sending a signal to a house mixer in live situ-

ations.

Wiring for the XLR connector is American standard (as follows):

Pin 1 = ground, Pin 2 = +, Pin 3 = -

TUNER OUT

The "Tuner Out" send jack allows the user to connect their instrument tuner to the Workingman's 2004 without having to unplug

and go back and forth from amp to tuner to amp. Like the Balanced D.I. output, this feature is isolated from the rest of the circuitry

and no other controls other than your instrument have an affect on this feature. Being on a sidechain (isolated) also avoids loading

down of the instrument causing a loss in its dynamic range.

To use this feature, plug in a shielded patch cord from this jack to the INPUT of your tuning device. Turn the amp on and you're

ready to go. If you don't want to monitor your sound while tuning, turn down the Master Volume control or position the selector

switch on the back panel to the "headphones" (middle) position.

INPUT JACKS

Two separate and independent input jacks are provided so that the best signal to noise ratio can be obtained without overloading

the preamp section. The Passive input has over twice the gain than that of the Active input. Both inputs can be used simultaneously

without affecting the volume or tone of the other. One use of these inputs would be to plug your bass into the Passive input and

practice along with a drum machine by plugging it into the Active input. Please see below for a detailed explanation of these inputs.

PASSIVE/ACTIVE INPUT

This input can and should be used if your instrument has passive electronics (no built-in preamp). Some pickups, such as EMG, etc.,

employ batteries for operation and will work perfectly using this input. Technically speaking, this input should be used if your instru-

ment has an output voltage of 1 volt RMS or LESS. Consult the owner's manual that came with your instrument or ask the manu-

facturer if you are unsure.

Please Note: Generally speaking, you should try the Passive input jack first. Some built-in preamps, such as those made by

Bartolini and Music Man, can be used with this input depending on their internal gain settings. If you hear a small amount of distor-

tion and the Preamp Clip LED is not activated, try using the Active input jack. And please note, some passive pickups DO distort.

Because of the hi-fi nature of all SWR products, even the smallest amount of distortion originating at the source (instrument) may

be heard.

ACTIVE INPUT

The Active input jack should be used with instruments having a built-in (on-board) preamp that will produce signals over 1 volt

RMS. Known basses that should use the Active input only are the Kubicki X-Factor and some Ovation electrics. Some really "hot"

pickups installed in your instrument may find the Active input more compatible. The best judge is your own ears.

Please Note: Using the Active input with passive basses may result in a loss of high-end transients. Players who roll off their

high-end starting at around 2K to 3KHz may find this input more to their liking.

If you hear some distortion from your active bass and are using the Active input jack, CHECK YOUR BATTERY!! Also, make sure the

Preamp Clip LED is not lighting.

PREAMP CLIP LED

The Preamp Clip LED will light whenever the Preamp, Tone section or output buffer reach clipping (run out of headroom). In the

event the Preamp clip indicator lights, turn down the Gain control. Since the Preamp Clip also monitors the Tone section, boosting

any one of the tone controls can cause the LED to activate. Again, turn down the Gain control if this happens.

Please Note: Constant clipping of the preamp will not harm the electronics in your Workingman's . However, damage can

occur to speakers due to near-DC content present in a clipped waveform. Do not defeat the limiter when overdriving the preamp.

GAIN CONTROL

The gain control adjusts the volume of the preamp section. After the Tone controls, Aural Enhancer and any effects you may be

using have been set to your liking, the Gain control should be set to where the Preamp Clip LED barely flashes upon hitting your

loudest note. After setting the Gain, use the Master Volume to set the desired volume level. Using these controls in this manner

assures the maximum signal-to- noise ratio with no distortion caused by the preamp circuits clipping. Since the Gain control is simi-

lar to a "pad", a small amount of signal will get through with the Gain control turned all the way down. The Gain also adjusts the

level sent to the Effects send jack. If your effect is being overdriven, turn down the Gain Control.

USING THE TONE CONTROLS

To get the most out of the Tone Controls of your Workingman's , it would be best to first understand how the Aural Enhancer

works, and how it interacts with the Bass, Midrange and Treble controls. Think of it as a variable tone curve, changing with its posi-

tion. As you raise the control from its "0", or fully counterclockwise position, you are elevating the whole range of sound (lows,

mids, and highs) at frequency points different than those selected for the individual Tone Controls. This remains true up to about

the "2 o'clock" position, at which point the mids start to drop off. The curves involved here are gentle, as opposed to the very

extreme curves you can create with the Tone Controls. Most significantly, the Aural Enhancer will raise the low end at a point lower

than the Bass control itself. For a 4-string bass, the Bass control itself will suffice. For the 5-string player, the Aural Enhancer will

help bring out the fundamentals of your instrument in the 30-60Hz range.

BASS CONTROL

The Bass control itself, as stated above, works in a range that will be useful under most "normal" conditions. Its musical use might

be thought of as a "fatness" control. Leaving the Aural Enhancer in a position lower than 12 o'clock will not boost the extreme bot-

tom so much as to make indistinct the working of the Bass control. The overall "punch" of your instrument, from your low E-string

on up about two octaves (midway up the G- string), will be determined with this control. With passive instruments, this will be

straightforward. With active instruments having bass-boost controls more exploration will be worthwhile. (Some active tone circuits

have boost-cut controls such as Tobias, Sadowsky, etc. Others such as Music Man, may be straight boost controls).

MID RANGE CONTROL

The Mid Range control operates in a crucial area for most instruments. Many basses, particularly with roundwound strings, can

have a very "honky", or nasal, sound. Dropping the Mid Range control can go a long way toward smoothing out your tone. We sug-

gest, though, that what sounds best when your listening to your tone by yourself may not be what works best in a band or record-

ing. Sometimes that objectionable quality may be just the right "hair" on your note to still have an audible presence in the track or

on stage.

TREBLE CONTROL

The Treble control operates in a tonal area that extends through and beyond the usual Treble control range. The Transparency

control "kicks in" at a much higher frequency. Boosting the control will open up the sound of a dull instrument, particularly in con-

junction with a tweeter, should you have one in your speaker system. However, this is also the range of string rattle, finger slides,

pickup clicks, etc. Again, we recommend you experiment with the control alone with your instrument while finding your tone, and

listen again in a band context, both near to and away from your speaker system. Qualities like punch, fatness, presence and bite

can be fairly well spread out. Treble, despite the broad dispersion of most tweeters, is a very directional quality. Spend some time

exploring what you can hear in this area as you move around.

AURAL ENHANCER

The Aural Enhancer was developed to bring out the fundamental low notes of the bass, reduce certain frequencies that can

"mask" fundamentals and enhance the high-end transients. The effect becomes more pronounced as the control is turned up. The

result is a more transparent sound. Listening to a passive bass with the control set all the way down, and then turning it all the way

up, can be likened to listening to the bass suddenly become "active".

TONE CONTROL SECTION

The Workingman's Tone Control section is a four-band set of level controls centered around the frequencies 80 Hz (Bass), 800 Hz

(Mid Range), 2KHz (Treble) and 5KHz (Transparency). Each control can cut or boost its band a maximum of 15dB. Each control has

a flat (center click) position that defeats its function. In this position, the tone controls are inactive.

For each tone control, rotating the knob counter-clockwise from the center "click" position will reduce or cut its designated fre-

quency. Rotating the knob clockwise will boost its designated band or frequency.

EFFECTS BLEND CONTROL

The Effects Blend control mixes the signal coming from your instrument with the sound coming from your effect. With the Blend

control fully counter-clockwise, no signal from your effect will be heard. As you turn this control clockwise, more of the effect can

be heard in the overall sound. When the Blend control is fully clockwise, no dry or unaffected signal is heard other than the output

of your effect device.

This type of control and patching arrangement is very effective in reducing noise caused by effects devices and in maintaining a

more natural sound. If your effects device has a similar control, we suggest leaving it set to its maximum effect/minimum dry sig-

nal position and using the Effects Blend control for this function. Please read the "Effects Loop" section for more information.

LIMITER DEFEAT

Pulling out the Effects Blend knob until a click is heard deactivates the Internal limiter circuit. Pushing the control back in, activates

the circuit.

MASTER VOLUME

The Master Volume adjusts the signal level going to the power amplifier. It DOES NOT control the output of the effects send jack or

Balanced Direct Record XLR output. It DOES affect the output at the "Speakers" jacks and headphones jack. Losses caused by

effects units can be recovered by increasing the Master Volume.

LIMITER CIRCUIT

This circuit is located after (post) the Master Volume and before (pre) the power amplifier. Therefore, the circuit is driven by the

Master Volume. Its threshold (starting point) is preset by the factory so that the user can get maximum overall apparent volume

without unduly overdriving the power amplifier or internal speakers. This feature may be defeated by pulling out the Blend control.

Please see the "Blend Control" section for further information.

LIMITER ACTIVE LED

When the threshold of the Limiter circuit is reached the green Limiter Active LED will light.

SPEAKER ON/OFF SWITCH

The top position labeled "ON" completes the circuit from your power amplifier to the speaker jacks located on the back panel. In

other words, in turns your speakers on (provided they are hooked up). The bottom position labeled "Speaker" (down) interrupts

this path and turns your speakers off. The "Speaker" (down) position allows you to: tune up silently; use headphones "only" with

speakers still plugged in; change or add speaker cabinets with the unit still on; silent turn-on or turn-off transients.

If no sound is coming from your speakers, check the position of this switch. If the switch is in the “ON” position, check the speaker

fuse, cables, etc.

Please Note: This switch does NOT affect the Headphone jack.

STEREO HEADPHONES JACK

By inserting a set of stereo headphones into this jack you will be able to monitor your sound or practice without disturbing your

neighbors. The headphone volume level is adjusted by the Master Volume. We suggest you begin with the Master Volume full off

(counter-clockwise), then slowly bring up the volume to the desired level. If you hear some distortion in your headphones that is not

present with the speakers on, turn down the volume as you are probably overdriving your headphones and could ruin them.

Any impedance headphones will work. However, optimum impedance is 75 ohms.

WARNING: DO NOT USE MONO HEADPHONES. USE STEREO HEADPHONES ONLY!

POWER SWITCH

Pressing the Power Switch to the ON position activates the Workingman's electronics as indicated by the switch itself illuminating

in red.

Please Note: Because of the tight regulation in the power supply, a transient (pop) may occur when turning the unit on or off .

This is normal and will not harm you speaker. If you wish to avoid this condition, turn the Speaker Switch to the "Stand By" position

before turning the unit on or off.

REAR PANEL FEATURES

EFFECTS LOOP

The Effects Loop is located POST EQ and PRE Master Volume in the signal path. The level appearing at the Send jack is controlled

by the Gain control on the front panel. If you are getting too hot a signal to the input of your effect, reduce the level of the Gain con-

trol and raise the level of your Master Volume control to retain similar overall volume levels. By using the Gain, Master Volume and

Effects Blend controls, optimum performance should be easily obtainable with any effects device.

The Effects Loop is designed as a "sidechain" (parallel) function similar to those found on mixing consoles. Use of the Effects

Loop should greatly reduce noise generated by effects devices (as compared to in-line effects loops). Additional features of this

type of loop can be found below under the Receive jack section.

SEND JACK

Run a shielded patch cable from the Send jack to the input of your effects device. This jack may be used as an additional line level

output, in which case its level is determined by the setting of the Gain control.

RETURN JACK

Run a shielded patch cable from the output of your effects device to the Return jack.

WORKINGMAN’S 2004 • 7

One unique feature of the Return Jack is the ability to practice along with pre-recorded music. Insert a sound source into the

Return jack (make sure it is a mono source). Use the Effects Blend control to mix the level of the recorded music with your instru-

ment's level. The combined signal will be heard through your speakers, headphones, or both. The send jack is not used.

Please Note: Inserting a plug into the Return jack activates the Effects Blend control by receiving a "command" through the

ground created. Therefore, only a mono (2-conductor) phone plug should be used. If you have a stereo (3-conductor) plug only, tie

the ring and the sleeve (ground) together.

If you are not getting any "effect" through the speakers, check the position of the Effects Blend control.

SPEAKER JACKS

Use an unshielded 2-conductor cable (NOT A GUITAR CORD!) to connect any speakers to your Workingman's . Use a high quality,

heavy gauge cable of at least 18 gauge (the lower the gauge, the heavier the cable). The total impedance of the speakers should

be 4 Ohms or greater. This means you can use one 4 ohm cabinet, two 8 ohm cabinets or four 16 ohm cabinets.

RECOMMENDED SPEAKER ENCLOSURES FROM SWR INCLUDE:

Any two of the following 8 ohm enclosures:

Workingman's 2x10T, Workingman's 4x10T, Workingman's 1x15T, Goliath III, Son Of Bertha, Big Ben Subwoofer and Goliath Jr. III (8

ohm version).

Any one of the following 4 ohm enclosures:

Big Bertha, Goliath Senior, Henry 8x8, Triad I or Goliath Jr. III (4 ohm version).

SPEAKER FUSE

The speaker fuse is provided to protect the power amplifier from a fault in the speaker cable or the speakers themselves. It can

also open (blow) if an impedance less than 4 ohms is used or in the unlikely event of a power amp failure. Size and rating of the

fuse is 3AG, 6 AMP FAST BLO. Do not defeat the purpose of this feature by using a higher rated fuse.

A/C LINE FUSE

This fuse is provided to protect the internal electronics against power surges, etc. It also protects the unit against

itself should one of the internal components fail. If this fuse should open, replace it with the same type of fuse

and rating. Do not defeat the purpose of this feature by using a higher rated fuse as it can void your warranty.

Proper rating of the fuse is as follows:

United States (120V): 3AG 4 amp, slo-blo

Europe (230V-240V): 3AG 2 amp slo-blo

A/C LINE CORD RECEPTACLE

Accepts a standard A/C power cable (supplied with the Workingman's in the United States), used with almost all current musical,

professional and household electronic devices. We recommend taking great care when packing up. Put the cable in your instru-

ment case, accessory case, etc. If it does become misplaced, replacement will be easy at almost any appliance store, super mar-

ket or the like.

Please Note: the rating for this cable is 3-conductor, 10 amperes. This is a rating of the current capacity of the cable, desig-

nated for higher power-drawing devices like amplifiers. If replacement is necessary, or if you wish to buy a longer cable, look for

the rating on the cable and be sure it is at least 10 amps.
